Cleaning CD/DVD
A dusty CD/DVD-ROM or dust-accumulated tray causes the device to fail to read data correctly.
Follow the procedure below to clean the tray and CD/DVD-ROM regularly:
1. Make sure that the server is powered off (the POWER LED is unlit).
2. Press the tray eject button on the front of the DVD drive. The tray comes out.
3. Hold the CD/DVD-ROM lightly and take it out from the tray.
4. Wipe the tray with a dry soft cloth.
5. Gently push the tray to retract it to the tray.
6. Wipe the signal side of the CD/DVD-ROM with a dry soft cloth.
IMPORTANT:
Do not touch the signal side of the CD/DVD-ROM with your hand.
IMPORTANT:
Do not wipe the lens of the DVD drive. Doing so may damage the
lens and may cause a malfunction of the drive.
IMPORTANT:
Wipe CD/DVD-ROMs from the center to the outside.
Use only CD/DVD-ROM cleaner if necessary. Cleaning a CD/DVD-ROM
with record spray/cleaner, benzene, or thinner causes damage to the
CD/DVD-ROM contents. At worst, inserting the CD/DVD-ROM into the
server may cause failure.
